Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients who have undergone a CT scan of the chest with visualization of the celiac trunk within the past year and are scheduled for transfemoral angiography.
✕Probably not a fit
Patients with limb amputations or known aortic abnormalities such as aortic aneurysms or dissections may not benefit from this study.

What this trial studies
This observational study aims to determine the most accurate methods for sizing intra-aortic balloon pumps (IABP) in patients undergoing transfemoral angiography. Researchers will evaluate various measurements, including patient height and specific anatomical distances obtained from chest X-rays and CT scans, to find reliable surrogates for IABP sizing. The study will involve patients who have had prior CT scans of the thoracic aorta and will undergo angiography, allowing for direct measurement of vessel distances. The goal is to improve the accuracy of IABP sizing to prevent complications associated with malpositioning.
Why it matters
Potential benefit: If successful, this study could lead to improved outcomes for patients requiring intra-aortic balloon pump support by ensuring proper sizing and positioning.
How similar studies have gone: While previous studies have explored IABP sizing, this approach of combining multiple anatomical measurements for improved accuracy is relatively novel.
